(a) Determine the state controllability and observability for the system represented by the following state equation. $$ \begin{gathered} X=\left[\begin{array}{ccc} 0 & 1 & 0 \\ 0 & 1 & 1 \\ 0 & -2 & -3 \end{array}\right] x+\left[\begin{array}{l} 0 ...
(a) A unity feedback system is given as $G(s)=\frac{5}{s(s+5)}$. The input to the system is described by $r(t)=6+5 t$. Find the generalized error coefficients and steady state error.
(b) Consider a unity feedback system with open loop transfer function, $G(s)=10 /(s+1)(s+2)$. Design a PI controller so that the closed loop has damping ratio of 0.707 and natural frequency of oscillation as $1.2 \mathrm{rad} / \mathrm{sec} .10$ ( $\...
